Lithium Sulfur Cell

Abstract: The invention relates to a lithium sulfur cell, a method of preparing a lithium sulfur cell, and a battery comprising the lithium sulfur cell. The lithium sulfur cell comprises a working electrode comprising a film comprising stacked layers of a metallic phase transition metal dichalcogenide of formula (I): LiaMX2 where a is from 0.0 to 2.0, X is selected from S, Se and Te, and M is a transition metal, such as Ti, Hf, V, Nb, Ta, Mo, W, Tc, Re, Pd or Pt. The method of preparing a lithium sulfur cell comprises: exfoliating a transition metal dichalcogenide to provide a metallic phase, transition metal dichalcogenide of formula (I); assembling a working electrode comprising a film comprising stacked layers of the metallic phase transition metal dichalcogenide and sulfur or a lithium (poly)sulfide; and assembling a lithium sulfur cell comprising the working electrode, a counter electrode, and an electrolyte.
